Howdy ya'll,
I'm trying to fix the issue in this JIRA:
https://issues.apache.org/jira/browse/PIG-3093
I got the plan at one point, as saw this:
#-----------------------------------------------
# New Logical Plan:
#-----------------------------------------------
D: (Name: LOForEach Schema: B::field1#4:chararray,field2#4:chararray)
| |
| (Name: LOGenerate[false,false] Schema:
B::field1#4:chararray,field2#4:chararray)
| | |
| | B::field1:(Name: Project Type: chararray Uid: 4 Input: 0 Column:
(*))
| | |
| | A::field1:(Name: Project Type: chararray Uid: 4 Input: 1 Column:
(*))
| |
| |---(Name: LOInnerLoad[B::field1] Schema: B::field1#4:chararray)
| |
| |---(Name: LOInnerLoad[A::field1] Schema: A::field1#4:chararray)
|
|---C: (Name: LOJoin(HASH) Schema:
A::field1#4:chararray,B::field1#4:chararray)
| |
| field1:(Name: Project Type: chararray Uid: 4 Input: 0 Column:
field1)
| |
| field1:(Name: Project Type: chararray Uid: 4 Input: 1 Column:
field1)
|
|---A: (Name: LOLoad Schema: field1#4:chararray)RequiredFields:null
|
|---B: (Name: LOForEach Schema: field1#4:chararray)
| |
| (Name: LOGenerate[false] Schema: field1#4:chararray)
| | |
| | field1:(Name: Project Type: chararray Uid: 4 Input: 0
Column: (*))
| |
| |---(Name: LOInnerLoad[0] Schema: field1#4:chararray)
|
|---A: (Name: LOLoad Schema: field1#4:chararray)RequiredFields:null
Noting that the Uid is repeated (because the 2 fields are derived from the
same field). I'm not sure if this is the source of the error, but since I
do not yet know what the error is I thought I would ask about it, as I do
not well understand the role of the uid, but it comes up a lot in the
LogicalPlan.
Thank you!
Jon
